Boston (WTSP/WBZ) -- Boston Police say three more suspects connected to the Boston Marathon bombing have been taken into custody.

Police made the announcement on Twitter Wednesday morning, saying more details would follow. According to CBS News, the arrested are three friends of Dzhokhar Tsarnaev. The charges are related to incidents after the bombings and interfering with investigators.

THE SUSPECTS

Azamat Tazhayakov and Dias Kadyrbayev, 19, both of New Bedford, are
charged with conspiracy to obstruct justice by conspiring to destroy,
conceal and cover up tangible objects, such as a laptop computer and a
backpack containing fireworks, belonging to Tsarnaev.

A third suspect, Robel Phillipos, 19 of Cambridge, is charged with
willfully making materially false statements to federal law enforcement
officials during a terrorism investigation.

After the arrests were announced, Boston Police said there is no threat to the public. The three are expected in federal court in South Boston Wednesday afternoon.

Azamat Tazhayakov and Dias Kadyrbayev are originally from Kazakhstan.

They entered the United States on student visas. Kadyrbayev and
Tazhayakov face maximum sentences of five years in prison and $250,000
each in fines.

Phillipos faces a maximum sentence of eight years in prison and a $250,000 fine.

THE COMPLAINT

According to the complaint unsealed Wednesday afternoon, Tazhayakov
and Kadyrbayev admitted to investigators they agreed to get rid of
Tsarnaev's backback "after concluding from news reports that
Tsarnaev was one of the Boston Marathon bombers."

When the FBI released the first photos of the bombing suspects at 5
p.m. on April 18, Kadyrbayev allegedly "texted Tsarnaev and told him
that he looked like the suspect on television."

Tsarnaev repsonded with "lol" and other statements Kadyrbayev interpreted as jokes.

About an hour later, Tazhayakov, Kadyrbayev, and Phillipos went to
Tsarnaev's dorm room. His roommate let them in and told them Tsarnaev
had left a couple of hours earlier. They stayed and watched a movie.
It was during this time, according to the complaint, they saw a
backpack containing fireworks.

"The fireworks had been opened and emptied of powder. Kadyrbayev knew
when he saw the empty fireworks that Tsarnaev was involved in the
Marathon bombing," the complaint stated.

Kadyrbayev removed the backpack from the room "in order to help his
friend Tsarnaev avoid trouble," investigators said. He also took
Tsarnaev's laptop and some Vaseline they believed was used to make the
bombs.

The three went back to Tazhayakov and Kadyrbayev's apartment, watched
more coverage of the manhunt for the suspsects and then decided to
throw the laptop and backpack in the trash in a dumpster around 10 p.m.,
according to the court documents.

They watched a garbage truck empty that dumpster Friday afternoon.

Authorities had recently searched a landfill near UMass-Dartmouth.
They revealed in the affidavit that the backpack was found there on
Friday, April 26. Inside were firewworks, a jar of Vaseline and a
homework sheet from a class attended by Tsarnaev at UMass-Dartmouth.

Earlier Wednesday, lawyers for Tazhayakov and Kadyrbayev said their
clients have been extensively interviewed by federal investigators.

The two men appeared via video for a visa violation hearing in immigration court in Boston on Wednesday.

They have been held in a county jail for more than a week on
allegations that they violated their student visas while attending
UMass-Dartmouth with Dzhokhar Tsarnaev.

The marathon attack was not mentioned in court and their cases were continued.

Their attorneys said afterward that authorities have not indicated
their clients had anything to do with the bombings. Federal authorities
would not comment.

Attorney Robert Stahl said Tazhayakov and Kadyrbayev were drawn to Tsarnaev because he also spoke Russian.
